ATTACHMENT FOR CONVERTING THE ORDINARY INTO A TAPER VISIE.

Specification of Letters Patent No. 9,429, dated November 30, 1852.

To all whom t may concern.'

Be it known that I, JEREMY W. Buss, of Hartford, county of Hartford, and State of Connecticut, have invented a new and useful Improvement in Vises for Mechanicians Uses; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view, Fig. 2 is a top View.

The nature of my invention consists in supplying a cheap and simple attachment to any kind of vise, even though already'set up and in use in the workshop, for thepurpose of enabling it to hold firmly and with-` out bruising articles of a tapering or other irregular form, which attachment is removable at pleasure, leaving the vise free to be used in the ordinary manner, and unimpaired in eiiiciency for customary purposes. I accomplish this by attaching to the hind or stationary jaw of the vise a saddle or clamp secured to the vise by the set screw (c) and in or to such saddle or clampl iix by a step at (d) a triangular piece of steel (a) or other material with its short sides curved or otherwise. It will be observed that the piece of steel (a Fig. 2) rests against the stationary jaw of the vise and by a rocking motion on its obtuse angle adapts itself, as the jaws approach each other to the wedge (e Fig. 2) or other irregularly shaped article required to be held.

In the above description as in the accompanying drawings I have attached the clamp (b) to the hind jaw by a set screw (o).

I use other methods of applying the attachment, varying with the kind of vise, as

for instance the clamp or saddle might rest without any set screw, directly upon the case of the screw of those descriptions of vise which have a square case covering the screw, or the triangle piece of steel, disconnected from the clamp or saddle, might have a hinge in its obtuse angle attached by a hook over the hind jaw of the vise, being thus retained in the same relative position to the jaw, and rocking against it as above.

Vises have heretofore been modied for the purpose of holding irregular shapes, but always so as to imply a change in their construction, and have never come into general use, because from their consequent complication the cost of manufacture was too sensibly increased, and they were more liable to get out of repair or because they could not be used for some customary purpose such as holding an article to be struck with a hammer, or a small parallel sided article.

That I claim as my invention and desire to secure by Letters Patent, is-

An attachment to the vise substantially as herein described, and for the purposes setforth, which attachment is removable at pleasure, and requires no change in the construction of the vise to which it is applied.
